CLAMP FOR HOSE-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 517,128, dated March27, 1894..

Application filed May 15, 1893- To all whom it may concern.-

Be it known that I, FRANK D. TAYLOR, a citizen of the United States ofAmerica, residing at Colorado Springs, in the county of El Paso andState of Colorado, have invented certain new and useful Improvements inClamps for Hose-Couplings; and I do declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in clamps for hose couplings, andthe object of this improvement is to provide a device of this classwhich shall be simple in construction, economical in cost, reliable,durable, efficient and easily applied.

To these ends the device consists of the features hereinafter describedand claimed, all of which will be fully understood by reference to theaccompanying drawings in which is illustrated an embodiment thereof.

In the drawings Figure l is a side elevation of the clamp in place uponthe hose. Fig. 2 is a sectiontaken through the coupling, the clamp beingshown in elevation. Fig. 3 is a section taken on the line 0c-a:, Fig. 1.Fig. 4 is a section taken on the line y-y, Fig. 2. Figs. 5 and 6illustrate modified forms of construction. Fig. '7 is a section taken onthe line 19-11:), Fig. 5. Fig. 8 is a section taken on the line zz, Fig.6. 'Fig. 9 is a detail view illustrating the double form of clamp.

Similar reference characters indicating corresponding parts or elementsin these views, let the numeral 5 designate the hose, and 6 the metalpart placed with the hose at each joint.

The clamp is composed of a band 7 and a movable clasp 8 apertured toreceive a screw 9 made fast to the band. The clasp is adjustable by theuse of a nut 10 located on the screw outside of the clasp which consistsof a segment of a ring or band provided with outer depending flangeswhich engage the hose, and between which the band passes as the clamp istightened by turning the nut. Instead of the solid band shown in Figs.1, 2, 3 and 4:, a divided band or double ring of the construction shownin Figs. 6 and 8, may be Serial No. 474,313. (NomodeL) employed, or itmay consist of a single ring circular in cross section as shown in Figs.5 and 7. In the form shown in Fig. 9, the band 7 is provided with twoscrews'9 located on diametrically opposite sides. Each of these screwsis engaged by a clasp 8. By the use of this form of device, adoubleclamping advantage is gained. It is believed, however, that thisform will never be needed on garden hose of ordinary size. I It may,however, be found advantageousin connection with the larger sizes.

From the foregoing description, the use of my improved clamp will bereadily understood. The ring or band '7 should be of such size that theextremities of the hose sections may be readily inserted therein. Theclasp 8 is then slipped over the screw 9 and the nut 10 placed upon thescrew extremity and turned down upon the clasp by the use of theordinary wrench. It will thus be seen that the adjustment of this clampis so simple that no special skill is necessary in applying it to thehose, while no tools except an ordinary wrench are necessary for itsadjustment. These advantages will be fully appreciated by those who havehad experience in using some of the devices heretofore placed upon themarket.

Having thus described my invention, what I claim is 1. A hose clampcomposed of a ringor band provided with a screw or threaded projection,a segmental clasp having flanges to bear upon the hose and a fasteningnut, substantially as described.

2. As an improved article of manufacture, a hose clamp composed of aring or band to encircle the hose and provided with a threadedprojection, a segmental clasp provided with outer depending flangesbetween which the band-passes,the clasp being apertured to receive thethreaded projections on the ring, and a tightening nut screwed upon theprotruding extremity of said projection, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
